IMPROVED COMPOSITION FOR MANUFACTURING STONE, AND FOR OTHER PURPOSES.

Specification forming part of Letters Patent No. 74,587, dated February18, 1868.

To all whom it may concern:

-Be it known that I, ANTONIO PELLETIER, of \Vashington, in the Districtof Columbia, have invented certain new and useful Improvements inComposition for Coating Wood, Cloth, Leather, Stone, Glass, &c.; and Ido hereby declare that the following is a full, clear, and exactdescription of the same.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

My invention relates to improvements in the composition of matter forwhich Letters Patent were granted me, No. 63,087, dated March 19, 1867,and No. 71,210, dated N ovember 19, 1867.

\Vhile the compositions for which my patcuts were obtained answer wellfor the purposes for which they were designed, I have found, by furtherexperiments, that they may be materially improved.

'My composition, as now made, used, and treated with my latestimprovements, I find makes a perfectly fire-proof and water-proof coatinfor wood ariFother PQITShflblG materials, and is particularly suited forcovering roofs, floors, sidewalks, decks of ships, walls, tables, &c.,or for preparing artificial stone.

In making my composition, I take fifty pounds of ve etable fibrousmatter or instead of it, mineral as es us. or powt ered emerv, (or usethese ingredients all mixed together,) fifty pounds of soa )-St0ll, (orother talcosc silicates three ga ons 0t 1 uid silicate ot soda 0specific gravity 1.2 to IAI, SIX pounds oi lithar e and thoroughly mixand incorporate m r 1i together, till the whole mass becomes softand/plastic, by means of mechanical devices described in my formerpatents. The plastic composition thus made I apply, with properinstruments, to any kind of surface, be it wood, paper, pasteboard,cloth, leather, brick, stone, or metal, and then sufier i't'to dry andharden.

When I desire to make the coating not only fire-proof, but alsoimpervious to water and other fluids, I apply 0 1 as y, an aqueouszinc,) containing about ten per cent. of dry sait, repeating theoperation, if necessary. Solutions of sal ammouiac, chloride andsulpliafe of iron, chloride or other s dl'tsgf 'lad,

wharvesprotectin g them against the corroding action of water,especially by the addition or use of varnish or drying-oils. The mass isunsurpassed as a lining of safes, boxes, barrels, for coating thebottoms of ships, or for manufacturing artificial stone. In preparingstone, however, I employ, in addition to the ingredients alreadydescribed, sand, or other silicious cheap material, such as 1ron,s1aalumina, rubble or broken stone may 6- sorlption, Kc.

Having thus described my invention, what I claim is- 1. The compound,consisting of vegetable fiber, mineral asbestus, emery-powder,soapstone, silicate of soda, or potassa, and litharge, substantially asdescribed and set forth.

2. The compound, consisting of vegetable fiber, mineral asbestus, emery,soap-stone, silicate of soda, or potash, litharge, when manufacturedinto stone, (sand being used'in addition,) or when coated on wood,cloth, leather, brick, stone, metals, or other solid surfaces, andtreated with chloride of zinc, oxide of zinc, sal ammoniac, chloride andsulphate of iron, salts of lead and manganese, sulphite of lime,substantially as described, and for the purpose set forth.

3. I claim, as a new article of manufacture, the composition,substantially as herein described, and for the uses and purposes setforth.

ANTONIO IELLETIER.
